At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

While it doesn't offer any answers, it both thrills and makes you think.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
